Using the Brightness and Contrast Control
This Reference Guide provides information and procedures for the
Brightness and Contrast Control.
Kodak provides a set of default color tables with the scanner. These
tables are bundled and installed with the Scan Validation Tool (SVT).
A color table is a file that can be downloaded to the scanner which
contains the information required for the scanner to output the desired
representation of your color document.
If the default color tables do not meet your specific needs, this tool may
be used to create your own custom color table. This custom color table
can then be downloaded to the scanner and used in production.
The color table to be used for front and rear images are set
independently. When scanning, only one color table can be applied to
each image (front or back). You can use the same color table for both
the front and the back, or use one color table for the front and one color
table for the back.
Use the Scan Validation Tool or your own application to download a
color table to the scanner.
For more information regarding the Brightness and Contrast Control,
see Appendix A, Color Concepts.
IMPORTANT:
• The Brightness and Contrast Control is not color management
software. The output from the Brightness and Contrast Control
cannot be used to modify monitors or printers. It is only intended to
modify the color image as produced by the scanner.
• Images created using a custom color table created using a specific
monitor may appear differently when viewed or printed on other
monitors or printers.
• Images used in this Reference Guide are for concept purposes only
and do not represent the expected image quality.
• Creation, use and management of any custom color table is your
responsibility. Kodak provides no support beyond verifying scanner
functionality using Kodak default color tables.

2A-61506 September 2006
Before you begin Before using the Brightness and Contrast Control, it is highly
recommended that you review the information below.
• The Kodak Scan Validation Tool must be installed. This installation
includes the TWAIN Datasource and the Kodak default color tables.
Both the Scan Validation Tool and the TWAIN Datasource are
required to run the Brightness and Contrast Control.
• Be sure your scanner is in good working order, cleaned and
calibrated. Refer to your User’s Guide for maintenance procedures.
• Verify that your scanner is capable of receiving custom color tables
created using the Brightness and Contrast Control. If not, you should
select the appropriate table from the default color tables provided by
Kodak for your scanner. You cannot use the Brightness and
Contrast Control to modify the default color tables.See the chart
below to determine if your scanner has this functionality.
• Before you create a custom color table, it is recommended that you
scan a representative group of documents and run these documents
with each of the Kodak default color tables. Analyze these images to
determine if any of the default color tables meet your needs. If not,
you may want to choose the color table which is closest to meeting
your needs. This default color table would be a good table to use as a
starting point to create your custom color table.
• When scanning color images, the following settings, in addition to
color tables, will effect perceived image quality, resolution, color
sharpening, JPEG compression (Good, Better, Best). Do not change
the value of these settings when comparing color image results using
the Kodak default color tables.
• When using Brightness and Contrast Control to create your own color
tables, be sure to select the same resolution (DPI) you used when
evaluating the sample images with the Kodak default color tables.
Resolution is selected using the DPI option from the File menu.

Creating a custom
color table
After you have reviewed the “Before you begin” section, you will be
ready to start using the Brightness and Contrast Control.
Using a Kodak default
color table as a starting
point
Before you create a custom color table, it is recommended that you
scan a representative group of documents and run this group of
documents with each of the Kodak default color tables. Analyze these
images to determine if any of the default color tables meet your needs.
If not, you may want to choose the color table which is closest to
meeting your needs. This default color table would be a good table to
use as a starting point to create your custom color table.
1. Open the Brightness and Contrast Control application. The main
window will be displayed.
2. Select File>Select TWAIN Source. The Select Source dialog box
will be displayed.
3. Highlight the desired source and click Select.
4. From the File menu select File>DPI and choose the resolution
which you will use when capturing color images in your production
environment.
